Geometric Ring Mandrel — Triangular Steel Stick, 13 Inch, 10 mm to 21 mm Taper

Forge crisp, geometric ring shanks and bezels with this 13-inch triangular steel forming mandrel.

What it does

This hardened steel mandrel provides a precise, three-sided form for shaping sheet metal and wire into clean, angular profiles. Its smooth taper allows for controlled expansion and shaping, enabling the creation of sharp, defined edges essential for modern geometric designs. The solid steel construction ensures durability and consistent results when struck or worked with a hammer, making it a reliable tool for consistent output on the bench.

How to use it

• Secure the mandrel in a vice or clamp.
• Form metal around the taper to desired shape.
• Gently tap with a hammer for crisp edges.

Who it's for

This tool is indispensable for UK bench jewellers and silversmiths crafting contemporary geometric rings, pendants, or bezels. It’s ideal for intermediate to professional makers looking to precisely form angular components, replacing the need for complex multi-part construction or less precise shaping methods.
